You are not likely to find a rectangular dish with a glass lid. Try Corningware. Amazon.com has a large selection of cooking pans.
"Foggy Pyrex" typically refers to a cloudy or hazy appearance that develops on glass Pyrex baking dishes over time. This can occur due to mineral deposits from hard water, oils, or residue from food. Cleaning the Pyrex with vinegar, baking soda, or a commercial cleaner can help remove the foggy appearance.
Pyrex glass is designed to withstand sudden & drastic TEMPERATURE changes. Most glass will shatter with sudden temperature changes. Pyrex is not bulletproof. Most transparent bulletproof material (glass) is composed of several layers of plastic & glass sandwiched together. The plastic holds the glass together, while the glass absorbs a bullet's impact.
I would have to say Pyrex
No, not all glass is made from Pyrex. Pyrex is a brand name for a type of borosilicate glass that is known for its durability and resistance to thermal shock. There are many other types of glass with different compositions and properties used for various applications.
It's a special kind of glass that resists the breakage that would occur to regular glass if you tried baking in it or transferring it between extremes of hot and cold.
Pyrex dishes are made of a special glass that can withstand high heat without shattering. The unique composition of Pyrex allows it to expand and contract evenly, making it ideal for baking and cooking. This type of glass is also nonporous, so it does not retain odors or flavors from previous use.
Pyrex is borosilicate glass and like all glass does not absorb any chemicals.
Pyrex changed its glass formula in 1998 from borosilicate to tempered soda-lime glass.
Are you talking about Kitchen grade Pyrex (Tempered Soda Lime Glass) or Lab grade Pyrex (borosilicate glass)?Lab grade contains more metals such as boron, sodium, and aluminum making lab grade glassware better conductors of heat.Kitchen glassware do not conduct heat as well which prevents burning the bottom of whatever your baking.Both are less likely to break than other glass types.Exaxol Chemical Corporationhttp://www.exaxol.com
Pyrex is just a brand name of toughened, heat-resistant glass.
It is a glass formulated to resist thermal shock.
The refractive index of Pyrex glass is typically around 1.47 for visible light. This value may vary slightly depending on the specific composition and thickness of the Pyrex glass.
